An exemplary illuminating apparatus includes a light guiding plate, a light source facing a light input surface of the light guiding plate, and a complementary color element adjacent to the light source. The light source comprises a number of LEDs which emit light with at least two wavelengths. The at least two wavelengths light mix with each other to gain a white light. The complementary color element is configured for receiving light emitted from adjacent, outmost LED and converting the light into white light. The white light is reflected by the complementary color element and emits from the light guiding plate through the light output surface. The complementary color element includes a plurality of first and second complementary color zones arranged alternatively and in a line.

First, a substrate is provided, and a half-tone mask is employed to perform an exposing and developing process for forming a plurality of photoresist patterns having different thickness. Then, a flow process is performed to heat the photoresist patterns so that each photoresist pattern has a microlens surface. Following that, a metal plate is formed on the substrate for obtaining a plurality of patterns, which are opposite to the plurality of photoresist patterns, on the bottom surface. Finally, the metal plate is removed from the substrate, and combined with an insert mold.
